I looked at the driver source code and there is certainly an attempt to use a country code from NVRAM. But maybe it hasn't actually been read from NVRAM at the point this is done. 'US' seems to be the default if the country code is blank. Ben.
Please refer to the information on wireless.kernel.org: http://wireless.kernel.org/en/users/Drivers/brcm80211#Regulatory_ImplementationYou could investigate whether the NVRAM/SROM country code is indeed blank or really configured with 'US'. For the driver itself channel 13 can be used as long as your access point is transmitting beacons, because it is regarded as a passive channel.
Reading the logs listed in bug #622842 I would suggest running the following command after loading the brcm80211 driver:
$ iw set reg EU You should see following in the log:Apr 30 10:05:22 myhost kernel: [ 3967.072332] cfg80211: Calling CRDA for country: EU
